Anthropic takes its capabilities to the next level with Claude Opus 4.1, which builds upon the Claude Opus 4 model introduced in May. The new model promises significant advantages over its predecessor in three key areas:

• Task Initiative: Developing tasks more autonomously by taking initiative.
• Practical Coding: Developing functional and practical software projects for real-world problems.
• Advanced Reasoning: Developing more accurate logic and solutions to complex problems.

The new model, with improved performance in many areas, is now available to paid Claude subscribers. Claude Opus 4.1, which is also available to developers via the official API and the Amazon Bedrock and Google Cloud Vertex AI platforms, is expected to be further enhanced in the coming weeks.

Claude Opus 4.1 Comes with Small But Impactful Innovations

This technological leap comes with the challenges of growing popularity. Anthropic stated that demand for its coding-focused Claude Code service has far exceeded its expectations. The company emphasized that some users run the system 24/7, resulting in extraordinary costs.

In a striking example provided by Anthropic, it was stated that a single user on a $200 monthly plan costs the company tens of thousands of dollars in model usage. The company stated that such exceptional circumstances threaten the overall sustainability of the system, making the restrictions inevitable.

Anthropic anticipates that the new limits will affect less than 5% of existing users, and this step also aims to prevent policy violations such as account sharing or service resale.

How much does Claude Opus 4.1 cost?
The new weekly limits, which will vary depending on usage, are as follows:

• Pro Plan ($20 per month): 40 to 80 hours of use with the Sonnet 4 model.
• Max Plan ($100 per month): 140 to 280 hours of use with the Sonnet 4 model and 15 to 35 hours with the higher-end Opus 4 model.
• Max Plan ($200 per month): 240 to 480 hours of use with the Sonnet 4 model and 24 to 40 hours with the Opus 4 model.

Anthropic’s move highlights the critical balance between the costs of innovation and service continuity in the AI sector. The company emphasizes its commitment to providing a fair and sustainable service for all users while offering cutting-edge technology.
